Onahu Creek Tree Ring Chronology from 180 to -37 BP

217-year tree ring chronology from Onahu Creek, Colorado, provides paleoclimate data. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. The study was last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual tree ring width series.
• Calibrate climate models by comparing the chronology against known historical climate events.
• Analyze growth trends and extreme events (e.g., droughts) encoded in the ring width parameter.
• Establish a regional dendrochronological reference for cross-dating other samples from Colorado.

Strengths

• Covers a 217-year time period from 180 to -37 calendar years BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -37 BP, providing no data for recent centuries.
• Dataset is geographically limited to a single site (Onahu Creek, Colorado).
• Last update was in 1987, indicating potential staleness in metadata or documentation.
